It's a nice setup you have. I think there's a little overlap at all levels except putter, e.g. I think a slightly overstable mid can do 99% of the things an overstable mid can do, so I go without the overstable myself. I'm sure through your experience you've found reasons to carry what you do though. I'm more comfortable throwing the 1 midrange I throw all the time and putting extra hyzer on it.

Speaking hypothetically though, if you were to take 1 disc from each speed range, say the straightest one, how limited would you feel in terms of the shots you could confidently throw? Are there any particular shots you'd really be wondering how to approach? Or do the different stabilities more or less make things easier / more convenient for you.
